Application filed March 11, 1927. Serial No. 114,591.

This invention relates to a tube for holding paste and the like, thegeneral object of the invention being to provide means'for facilitatingthe ejection of the material from the tube, by means of a followerarranged in the tube and actuated by means of a threaded shaft which isrotated b a. knurled disk arranged'at the rear end 0 the tune.

to Another object of the invention is to provide means for holding thetube against a wall or the like in such a manner that the ccting meanscan beoperated to eject some of the material. from the tube withoutnecesl5 sitating the removal of the tube from the holder,

A further object of the invention is to provide means for indicatingwhen the tube is empty.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended clauns.

in describing my invention in detail reference will be had to theaccompanying rawings wherein like characters denote like or 39corresponding parts throughout the several views, and in which Figure 1is an elevation showing a number of tubes supported in a holder.

Figure 2 is a top plan view of Figure 1.

Figure 3 is an enlarged longitudinal sectional view through a tube.

Figure 1 is a fragmentary view showing the means for indicating when thetube is empty.

Figure 5 is a section on line 5-5 of Figure 3.

igure 6 is a view'of the nut member or follower.

In these views, 1 indicates the tube for i holding the paste or othermaterial, this tube being formed in the usual manner, except thatinstead of folding the rear end upon itself, I close said rear end-by acircular block or member 2 which is formed with an annular groovetherein so that a portion outer end of which carries a knurled disk 7which forms a handle whereby the shaft can be rotated. Washers 8 areplaced on the shaft, one on each side of the block and no .anut 9 on theshaft holds the parts together. A follower cl nut member 10 enga es thethreaded portion of the shaft and sai member has a notch-11 thereinwhich engages a longitudinally extending head 12 formed in 06 the tubeby grooving the same exteriorly.

Thus b turning the shaft, the member 10 will be ed toward the outlet endof the tube, due to its engagement with the the threaded portion of theshaftand also due to the fact that it is held against rotation by thebead en aging the notch 11, so that the material Wlll be forced from themouth of the tube.

When the follower nears the front end of 7 the tube, it will engage apin 13 mounted in said front endv and project the same, thus indicatingthat the tube is empty.

I also provide a holder 14 for supporting a number of tubes on a wall orother support,

said holder having semi-circular grooves 15 therein, each of which isadapted to frictionally hold a tube. The bottom of each groove has ateat 16 thereonfor enterin the groove in the tube formed by the bee. 12,B so that the tube is held against rotation in the holder when the shaftis turned to eject some of the material from the tube.

This holder, as will be seen, will support the tube in such a mannerthat the material can be jected therefrom on to a brush or the likewithout necessitating the tube bein taken from the support, it beingunderstoo that the tube is placed in the holder with its outlet endlowermost.

From the foregoing it will be seen that I have provided 'simple meansfor facilitatin the ejection of material from a tube an without handlingthe tube or taking it from its support, so that toothpaste, forinstance, can be easily and quickly applied to a brush.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that'I may 108 make changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall within the scope of the appendedclaims.

What I claim is: p

1. A tube of the class described having a closure in its rear end, ascrew shaft having v an unthreaded portion rotatably mounted in theclosure with a-threaded portion located in the tube, a follower in thetube .having a threaded hole therein engaged by the shaft,

I means for preventing rotary movement of .10 of the tube, forindicating that the tube is empty.

I 2. In a dispensing device of the character described, a tube having aconstricted charge end,'a block member secured within the other end ofthe tube, a shaft having a smooth portion rotatably engaged axially thrusaid block, a head carried by said shaft above and.

threaded portion of the shaft, and means mounted at the discharge end ofthe tube and positioned in the path of travel of the folower andprojectable thereby for indicating approximate emptiness of the tube.

In testimony whereof I afiix my signature.
